[0062] Referring to the above Table 1 and Table 2, it is remarkable that when Sodium N-cocoyl-methyl taurate (Test Example 1-1) or N-cocoyl glutamate (Test Example 1-2), as the anionic surfactant, and cocamidopropyl betaine, as the amphoteric surfactant, are formulated, the respective evaluation results can satisfy each expected criterion. However, when Sodium N-cocoyl glycinate (1-3 and 1-4) is used, the appearance turns cloudy despite applying an amino acid-based anionic surfactant. When sodium cocoamphoacetate (2-3) is used as the amphoteric surfactant, precipitates appear. When lauryl betaine is used as the amphoteric surfactant (2-1), the smooth rinsing drops slightly, but it is enough from practical use standpoints.

[0063] Thus, it is understandable that it is necessary to formulate N-acyl-N-methyl taurate (Sodium N-cocoyl-methyl taurate) or N-acyl-glutamate (N-cocoyl glutamate) as the anionic surfactant and alkamidopropyl betaine (cocamidopropyl betaine) or alkyl betaine (lauryl betaine) as the cationic surfactant.

[0064] Subsequently, the present inventor investigated sugars/sugar alcohols. The results are shown in Table 3.

[0065] Referring to the above Table 3, it is clear that sorbitol (1-1), maltitol (3-1) and erythritol (3-3) as the sugar/sugar alcohol bring in outstanding characteristics therefore, and fructose (3-2) and trehalose (3-4) bring in also sufficiently satisfactory results.

[0066] However, the evaluation results are not satisfactory when either the highly modified/altered hydroxypropyl cyclodextrin (3-5) or stearyl dihydroxypropyldimonium oligosaccharide (3-6) is applied.

[0067] Furthermore, the present inventor examined the formulation amount of sugar alcohols.

[0068] The results are shown in the following Tables 4-1 and 4-2.

[0069] Referring to the above Tables 4-land 4-2, the behaviors due to sorbitol and maltitol are similar each other, and results therefrom are good when the formulation amount thereof is in a range of 14% by mass (Test Examples 4-3 and 4-9) to 35% by mass (Test Examples 4-5 and 4-12).

[0070] Furthermore, the present inventor examined inorganic salts.

[0071] The results are shown in Tables 5 and 6.

[0072] Referring to the above Table 5, even when the formulation amount of inorganic salt is 0.1% by mass (5-1), results are good, but when the formulation amount thereof is reached to 13% by mass (5-4), the appearance is damaged. Thus, the upper limit of the formulation amount of inorganic salt is about 1.5% by mass.

[0073] Referring to Table 6, it is understandable that sodium sulfate, magnesium chloride, and ammonium chloride as well as sodium chloride can provide the similar effect.

[0074] In addition, the present inventor examined nonionic surfactants. The results are shown in Table 7.

[0075] Referring to Table 7, it is understandable that the nonionic surfactant having the fatty acid residue having 12 to 16 carbon atoms can excellently improve usability thereof.

[0076] Furthermore, the present inventors examined the kinds of cationized polymers and the formulation amount thereof.

[0077] The results are shown in Table 8.

[0078] Referring to the above Table 8, it is clear that not only cationic guar gum and cationic cellulose, of which natural polysaccharides are cationized, but also synthetic cationic polymers, such as methyl acrylate/dialkyldimethylammonium chloride copolymer, are applicable and useful, and the formulation amount in a range of 0.05 to 1% by mass, preferably 0.3 to 1% by mass, can provide preferable results.
